ARTHUR PETZENBURGER, OF BERLIN, GERMANY.

CONDUCTOR AND COLLECTOR FOR ELECTRIC RAILWAYS SPECIFICATION formingpartof Letters Patent No. 657,830, dated September 1 1, 1900.

Application filed December 8, 1899. Serial No. 739,706. LNo model.)

To ctZZ whom, it may concern:

BeitknownthatLARTHURPETZENBiiRGER, a subject of the King of Prussia,residing at Berlin, in the Kingdom of Prussia, Germany, have inventedcertain new and useful Improvements in Conductors and Collectors forElectric Railways, (for which I have applied for patents in Germany,dated September 4, 1899; in Austria, dated May 8, 1899; in Belgium, No.142,573, dated May 10, 1899, and in England, No. 9,938, dated May 11,1899,) of which the following is a specification.

A high electromotive force cannot be allowed by the authorities in thecase of overhead or rail conductors because of the danger to which thepassengers and staff would be subjected.

The object of this new construction is to remove this greatdisadvantage, which is especially felt on long lines.

On Sheet 1 of the accompanying drawings, Figures 1 and 2 represent theentire arrangement of my invention diagrammatically. Fig. 1 is a partsection of the line, showing the protecting-case G, the conductors S,and the collector L at its extreme position. Fig. 2 is a front view ofthree current-collectors, arranged side by side, connected to the lowerframe ofthe locomotive. Fig. 4 is a section of the protecting-casing G,revealing aside view of the current-collecting arm A and thecontact-shoe H in several different positions. Figs. 5, 6, and 7represent elevations of the arm A, the contact-shoe H in the inactiveposition, and the connection of the latter with the flexible shaft w bythe intermediate member m m. Fig. 8 is a section of the currentcollectoron line a b of Fig. 5, showing a top view of the contact-shoe in theactive position. Fig. 3 is a front view of the rollerguide K and K and asection of the side arm L. Fig. 9 is a plan view of the roller-guide K Kand of the side arm- L. On Sheet 2 of the drawings Figs. 10, 11, and 12show a covering for the slot Sch.

My invention is characterized by the overground protecting-casing andthe threefold motion current-collector. The overground protecting-casingG, which is preferably arranged at the side of the rails, consists ofthe.

the current-collector itself it should first be stated-that each phaseof the conductor has its own collector, each of which latter permitsofathreefold motion and isadjustable. First, the contact-shoe H can berotated on the pin Z through about one hundred and twenty degrees;secondly, the arm A of the side arm L L, which is perpendicular in theactive position, can by rotation be moved into and out of theprotecting-casing G,and,thirdly,the use of the protected low conductornecessitates a movement of the side arm L L in a longitudinal directionto the extent of about one meter.

The contact-shoe H, which is formed from a corrugated copper plate, isprovided with a boss or cylindrical part at the one edge, through whichthere is a hole h. The latter is ground on the pin Z, so that thecurrent is transferred by the contact-shoe from the conductor to the pinZ with certainty, although the said contact-shoe can easily rotate onthe pin. When the contact-shoe H has been placed on the pin Z, theinsulatingbody I is secured to the same with the help of theintermediate piece m m and the screws 8 s or s, so that the three partsare united, can turn as one whole on the pin Z, and are supportedtogether by the middle stronger part c. To further secure thecontact-shoe on the pin Z, a screw-thread is provided at the end of thepin.

In the insulating-body I the flexible shaft w is secured. This shaftmoves in a tube thatv passes through the side arm, and it issues belowthe locomotive, from whence it passes to the cab or drivers position,where it can be actuated by the lever K. The engine-driver isaccordingly able to adjust the contact-shoe perpendicularly, as shown indotted lines in Fig. 4, or to let it down onto the conductor. Thecontact-shoe bears on the conductor by reason of its own weight, whichcan be regulated accordingly.

The collector-arm A and the side arm L are rigidly connected by theelbow M. Through both the side arm L and the collector-arm A the copperconductor a, which terminates in the pin Z, and the flexible shaft topass, being insulated from each other and from the outer protecting andsupporting tube. The. outer casing of the collector-arm A is of steel ofoval section and can therefore slide without hindrance in the slot Schof the casing G. Further, all obstructions that may arise from snow andice can easily be overcome by the same. The envelop of the side arm Lconsists of a double tube. The inner tube L, which incloses theinsulated conductor e and flexible shaft w, is rotatably supported inthe outer tube L by the rings 9 g, so that the engine-driver can bymeans of the rod F and lever B, which latter is secured to the tube L,rotate this said tube L, and thus also the arm A, moving the latter inor out of the protecting-casing G.

In Figs. 3 and 9 the roller-guide is'represented. This guide supportsthe side arm L and permits of its movement in a longitudinal direction,so that the arm A, sliding in the slot, can adjust itself to thevariations on the line between the casing G and the rails necessitatedby constructional considerations. At the points of variation theprotecting-casing G is strengthened, so that the collector may be safelyguided by the slot. The roller-guide consists of two rings R and R, ineach of which a number of rollers u u 'u are secured with screwadjustment. these rollers, which are screwed out to correspond with thecircumference of the tube L, the side arm is guided in a longitudinaldirection. The rings R and R are screwed on a plate P, which is rivetedto a beam secured between the bearings of two Wheel-axles.

The flexible shaft w will adapt itself to the movements of the side armwithout difficulty, and the current-conductor e is made with a fewcoils, so that it can likewise adjust itself without strain to the samemovements. By means of the rod F the collector can be turned axially andalso moved longitudinally, so that the engine-driver from his cab isable to turn the contact-shoe into and out of contact with theconductor, to turn the side arm at all distances of theprotecting-casing from the rails, and to control the same in alongitudinal direction (horizontally,) whereby the switching in and outof arm A is rendered possible.

The covering of the slot Sch, Figs. 10, 11, and 12, to be provided atstations, if necessary, consists of two elastic widths i 'i of linoleumor the like, which are riveted to the protecting-casing at distances offifty centimeters by springs f on the one side and hinges n on theother. The arrangement is such that the elastic width only undergoes af2 es /30 slight lateral movement on the collector-arm passing, whereasthe second width, which is attached by hinges and projects above thefirst, is turned back when the collector-arm passes through, beingclosed afterward by its own weight.

What I claim, and desire to secure by Letters Patent of the UnitedStates, is
